A system consists of two components. P(the 1st component functions in satisfactory manner during its design life)=0.75, P(at least one of the two components functions in satisfactory manner during its design life)=0.86, and P(both component functions in satisfactory manner during its design life)=0.65. given that the second component functions in a satisfactory manner throughout its design life, What is the probability that the first one does also?

Homework Answers

Answer #1

We have

P(the 1st component functions in satisfactory manner during its design life)=0.75

P(both component functions in satisfactory manner during its design life)=0.65.

We asked the conditional probability that second component functions in a satisfactory manner throughout its design life, What is the probability that the first one does also

P ( 1st component functions in a satisfactory /2nd component functions in a satisfactory manner)

= P( both components function in satisfactory manner)/P( 2 nd component function in a satisfactory manner)

= 0.65/0.75

= 0.8667

We have a system that has 2 independent components. Both components must function in order for the system to function. The first component has 9 independent elements that each work with probability 0.92. If at least 6 of the elements are working then the first component will function. The second component has 6 independent elements that work with probability 0.85. If at least 4 of the elements are working then the second component will function. (a) What is the probability...

A system consists of two identical pumps, #1 and #2. If one pump fails, the system will still operate. However, because of the added strain, the remaining pump is now more likely to fail than was originally the case. That is, r = P(#2 fails | #1 fails) > P(#2 fails) = q. If at least one pump fails by the end of the pump design life in 11% of all systems and both pumps fail during that period in...

Consider purchasing a system of audio components consisting of a receiver, a pair of speakers, and a CD player. Let A1 be the event that the receiver functions properly throughout the warranty period, A2 be the event that the speakers function properly throughout the warranty period, and A3 be the event that the CD player functions properly throughout the warranty period. Suppose that these events are (mutually) independent with P(A1) = 0.94, P(A2) = 0.96, and P(A3) = 0.90. (Round...

Suppose that a certain system contains three components that function independently of each other and are connected in series, so that the system fails as soon as one of the components fails. Suppose that the length of life of the first component, X1, measured in hours, has an exponential distribution with parameter λ = 0.01; the length of life of the second component, X2, has an exponential distribution with parameter λ = 0.03; and the length of life of the...

One of the large photocopiers used by a printing company has a number of special functions unique to that particular model. This photocopier generally performs well but, because of the complexity of its design and the frequency of usage, it occasionally breaks down. The department has kept records of the number of breakdowns per month over the last fifty months. The data is summarized in the table below:    Number of Breakdowns Probability 0 0.12 1 0.32 2 0.24 3...
